Image formats
JPEG and JPG files are common camera and phone exports. Fenwick DataClean removes common EXIF, XMP, Photoshop metadata, and comment segments. PNG and APNG files can contain text chunks, timestamps, EXIF, and private chunks. WebP and GIF files can include XMP, comments, and other metadata blocks depending on how the file was created.
Video formats
MP4, MOV, and M4V files are common outputs from phones, cameras, and editing apps. These containers can carry metadata atoms and text payloads that identify creation tools, timing, authorship, or export context. Fenwick DataClean focuses on removing recognizable metadata while preserving playable structure.
Unsupported or unusual files
Some files use proprietary structures, damaged containers, encryption, or metadata that must be handled by specialized offline tools. When a file cannot be safely cleaned in the browser, Fenwick DataClean gives a status note instead of pretending every format can be treated the same way.
Best everyday use
Use the cleaner for everyday public sharing: photos, screenshots, social assets, marketplace images, client media, product demos, short clips, and files that need a cleaner public copy. Keep originals in a private archive when you need untouched metadata for records.
How to choose the right file workflow
For photos and screenshots, clean after the image is final and before uploading. For videos, clean after the final export and then play the cleaned result. For files that are still being edited, keep metadata in the working copy until the project is complete. Cleaning too early can remove information that is useful during editing, while cleaning too late can allow private details to travel farther than intended.
Why unsupported files are handled carefully
A responsible cleaner should not guess when a format is unknown. Some files contain proprietary metadata, encryption, unusual container layouts, or damaged structures. Changing those files aggressively can cause corruption. Fenwick DataClean is designed to give a clear status note when a file cannot be handled safely in the browser, so users can choose a specialized offline tool if needed.
Format support will stay focused
The site prioritizes common formats people actually share: camera photos, screenshots, exported graphics, short clips, phone videos, and files prepared for public upload. Keeping the supported list focused helps the cleaner stay fast, understandable, and useful instead of becoming a confusing file conversion product.
Recommended verification by format
After cleaning JPEG, PNG, WebP, or GIF files, open the image and confirm that it displays correctly. After cleaning MP4, MOV, or M4V files, play the output and check audio, video, and seek behavior. This review is especially important before client delivery, public publishing, or archiving cleaned copies for future use.
Why file integrity comes first
Removing metadata should not come at the cost of broken files. When a browser-based cleaner cannot safely modify a file, a clear status note is better than forcing an aggressive rewrite. Fenwick DataClean is built around practical public-sharing cleanup, so preserving usable output is part of the feature, not an afterthought.
Use format support as a decision guide
If a file is listed as supported, use the cleaner on a copy and review the result. If a file is unusual or unsupported, avoid forcing it through a workflow that was not designed for it. That conservative approach protects both privacy and file usability.
